    # Reserved Test Domain Names #

    Making up fake email addresses that use real domain names is a bad idea and in my experience also extremely common. To help people avoid that situation, here is a list of all the domain names that I know of that are reserved explicitly for purposes like testing and documentation.

    ## Reserved Top-Level Domains ##

    ### .test ###

    Reserved by RFC2606/RFC6761.

    > ".test" is recommended for use in testing of current or new DNS related code.
    ### .example ###

    Reserved by RFC2606/RFC6761.

    > ".example" is recommended for use in documentation or as examples.
    ### .invalid ###

    Reserved by RFC2606/RFC6761.

    > ".invalid" is intended for use in online construction of domai names that are sure to be invalid and which it is obvious at a glance are invalid.
    ### .localhost ###

    Reserved by RFC2606/RFC6761.

    > The ".localhost" TLD has traditionally been statically defined in host DNS implementations as having an A record pointing to the loop back IP address and is reserved for such use. Any other use would conflict with widely deployed code which assumes this use.
    ## Second Level Domains ##

    ### example.com / example.net / example.org ###

    Reserved by RFC2606/RFC6761 for use in documentation and examples.
